fIPE-FITTING.

To all whom t may concern.:

Be it known that I, CHARLES J.- TRUEMAN,

la citizen of the United States, residing `at Baltimore, State of Maryland, have invented certain new and useful Improvements in Pipe-Fittings, of which the following is a specification.

The present invention has as its object to provide an improved form of T for establishing communication between the lead bend of a closet bowl and the soilpipe and likewise between the bath tub drain, lavatory drain, and if/desired a shower bath drain, and the said soil pipe.

Heretofore in establishing a connection of this kind one method of procedure has been to employ a T having a relatively short branch or bell to receive the discharge end of the lead bend which leads from the closet bcliwl and to wipe into the ylead bend the t e tory but is method has many disadvantages. To wipe the joints requires considerable time and it is not practicable to calk in the lead bend until these joints are wiped.'

connecting up the galvanized iron drain v pipes from the bath tub and lavatory basin. j

Also, w ere the branch or drain pipes are wiped i to. the lead bend, it is usually a difficult 'matter to throw the bend at an angle or beat it over to one side or the other to `obtain the desired connection especially if the partition which conceals the soil pipe is set too far away from the lead bend or too near the lead bend, as a uarter of an inch one way or the other will not permit the flush tank to set flush with the finished wall.'

Under these conditions the lead bend can be beat `one Way or the other but the iron bend would require to 4be melted at the calked joint "Where it enters the branch of the main T of the soil pipe and this would be a very difficult matter if the ldrain pipes from rain plipes from the bath tub and lava-` Specication of Letters Patent.

jet bowl with top flush connectionfrom the closet tank is used .as the distance must be exact, and wher@J a bend lies too close to the wall the closet seat will be prevented from tarliding up or lying back against the flush` I n view of the foregoing it is a further object of. the invention to provide a novel constructionof cast iron T for establishing communication between the soil pipe and the lead bend from the closet bowl and the drain pipes from the bath tub and lavatory or shower, the T being of such construction as to permit of the lead bend being calked into its branch asthe soil pipe or stack is being run up past the bath room and to a bath room on a higher floor, and which will also permit thel lead bend being more conveniently distorted to Vinsure proper connection than would be possible if the drain pipes from' the bath tub and lavatory were wiped iptolfor otherwise connectedv with the bend i se Another object of the invention `is to so construct the T as to practically dispense with the necessity of wiped joints in establishing communication between the drain pipes from the bath tub and lavatory and the soil pipe'or stack, the T being provided with the required number of branches which are threaded-to permit of the ready connectionl therewith of the threaded ends of the alvanized drain pipes leading from the ath tub and the lavatory.

A further object of the invention is to so construct the T that the branches into which the drain pipes from the bath tub and lavatory are connected, will be ositioned out of the way in calking the leadp bend into the main branch or bell of the T, these 'drain pipe branches being located in rear of the bell instead of in front of the bell as is usually the case. Likewise, the T is so constructed that the bell branch thereof will ex tend suficiently far from the vertical arm of the T asv to avoid any interference by floor joist, which is usually found close to .the -partition which conceals the vertical soil pipe, in fitting the drain vpipes to the v Fig. 3 isa horizontal sectional view taken substantially on the line 3--3 of Fig. 2 and looking in a downward direction,y and F ig. 4 is a view similar to Fig. 2, illustrating a slight modification of the invention.

ln the drawings, the numeral 1 indicates in general the T embodying the vpresent invention, provided at the upper and lower ends of its vertical arm 2 with the usual bells indicated respec-tively by the numerals 3 and 4 for the connection of the sections of the soil pipe or stack 5. The T 1 further includes the lateral arm 6 which has heretofore been made very short but in the present instance relatively long as clearly shown in Figs. 1 and 2 of the drawings. rlhis lateral arm is provided with a bell 7 at its outer end into which may be calked the discharge end-of the usual lead bend which is indicated by the numeral 8, the intake end of this bend being connected in the usual manner as at 9 with the down leg of the closet bowl which is indicated by the numeral 10, the said upper or intake end ofthe bend extending through an opening 11 in the bath room floor which is indicated by the numeral 12.

As heretofore stated, theold practice has been to provide a wiped jointl connection between the drain pipes leading from the bath tub and' lavatory or'shower bath and the lead bend 8 but in the present instance the lateral arm 6 of the T 1 is provided with short branches or nipples 13 and 13 which are formed integrally therewith and extend forwardly and laterally at an angle as clearly shown in Fig. 3 of the drawingsg lThese branches are interiorly threaded as at 15 to receive the threaded ends of drain pipes 16 and 17 which lead for example respectively from the bath tub drain and the lavatorydrain, or one may lead from a shower bath drain. @f course where there is no bath tub or where Ithere is no lavatory, only one of the branches 13 or 14 need be provided and therefore l am not to be limited to the number of branches illustrated in the drawings as the lateral arm 6 of theT may be provided with any required number of branches. The branches 13 are preferably located directly behind the bell 7 and in fact so close thereto that in the casting of the T the exterior surfaces of the branches will merge with the exterior surface of the bell as indicated by the numeral 18 so as to materially rein-force these arts.

It will be evident from the oregoing that by employing the T embodying t e present invention the connection ofthe drain pipes 16 and 17 in communica-tion with the T by wiping joints into the lead bend as has heretofore been done is obviated and thus considerable time is saved and roviding furv thermore for the connection o thesebranches without in any way interfering with distortion of the lead bend to properly seat lin that form of the invention shown in ,f

Fig. 4 of the drawings, a cast iron pipe 19 is substituted for the lead bend, the outlet end of this pipe being calked intothe bell 7 and the inlet end of the pipe being interiorly threaded as at 30 to receive the lower end of a nipple 21 which is connected as at 22 in the usual manner with the down leg of the closet bowl 10, as in a regular screw pipe o 3 Where more expensive bowls are required to be replaced, the bend requires to be moved for the reason that nearly all such bowls have top iiush connection with the. tank. rlhe T of the present invention is so constructed as to bring the branches 13 nearer to the soil pipe 5 and, thus minimizes the likelihood of stoppage of the, pipes which would9 on the other hand,'be likely to occur the branches 13 and 14 are located slightly above the center line of the branch or arm 6 of the T so as to obviate the necessity Aof cutting deeply into any ioor beams that may comein contact or be in the way ofthese branches under some conditions.

I From the foregoing it will be evident, that inasmuch as the arm 6 projects substantially horizontally at ri ht angles from one side of the arm l an has its outer end portion horizontally disposed and straight and terminating in the bell 7 which is presented laterally, the lead pipe bend 8 may, in accordance with common practice, be beaten over until its end isirmly seated in the said bell 7 and it is thus possible to accommodate for a variation of asmuch as two inches where the bowl connection is in the nature of a lead ipe bend. In the usual fitting, however, t e bell corresponding to the bell 7, is presented in an upward dlrection and therefore this advantage is not resent. Therefore in my improved fitting, 1n substituting one bowl for another, this may be accomplished readily b the useof a lead pipe bend andthen beating the bend overy until its end is positioned with relation to the fitting, there being no disturbance whatsoever of the drain pipe connections make the proper connection.

f13 and 14 are located bodily below the plane of the upper side of the arm 6 of the itting so the connection of the waste pipes 16 and 17 with these parts may be more readily accomplished than in a structure in which the drain pipe connections are formed upon and above the upper side of the arm and would therefore be located so close to the floor as to render it diiicult to It will be evident that the bell 7 is located a suitable distance from the stand pipe, by reason of the length of thel arm 6, so that the bell will be brought clear of the vfloor 14which is usually encountered in the installation of such 'a fitting and therefore, when the end -of the lead pipe bend is tted into the bell, the joint may be conveniently calked, which however is ,practically impossible of accomplishment in the use of a fitting in which the corresponding bell is presented in an upward direction.

What I claim as new is:

A pipe fitting comprising a T having a rela`- tively long laterally extending Iarm, the outer portion of which is strai ht and terminates in a laterallyv opening ell to receive one end of a lead pipe bend, the arm bein provided at a point inwardly of the sai bell end and below the plane of the upper side of the arm with means for the connection of a branchA ipe with the arm to lead at an angle there rom.
